The Commerce Insurance Company Asks Court to Review New 
Massachusetts Residual Market Rules


WEBSTER, Mass. -- Jan. 5, 2005 -- The Commerce Insurance Company, 
a wholly owned subsidiary of The Commerce Group, Inc. (NYSE -- 
CGI), filed an action today in Massachusetts Superior Court, 
Suffolk County, in response to the new rules published by the 
Division of Insurance for the automobile residual market system.  
Commerce is asking the Court to determine whether the new rules 
are consistent with longstanding Massachusetts laws.

Commerce has been active throughout the development of this 
residual market reform by testifying at each of the Division's 
three public hearings and submitting proposed rule amendments for 
consideration by the Division.  In response, the Division made 
many fundamental changes to the reform since first publishing its 
proposal last April.  While those revisions addressed some of the 
Company's concerns, Commerce is asking the Court to resolve a 
number of serious legal issues that arise from specific aspects of 
the new system.

The Commerce Insurance Company, which is rated A+ (Superior) by 
A.M. Best, is the principal operating subsidiary of The Commerce 
Group, Inc. headquartered in Webster, Massachusetts.  Additional 
property and casualty insurance subsidiaries include Citation 
Insurance Company in Massachusetts, Commerce West Insurance 
Company in California and American Commerce Insurance Company in 
Ohio.  Through its subsidiaries' combined insurance activities, 
Commerce Group is ranked as the 20th largest personal automobile 
insurance group in the country by A.M. Best, based on 2003 direct 
written premium information.

COMPLAINT AND APPEAL FROM DECISION AND 
ORDER OF THE COMMISSIONER OF INSURANCE

INTRODUCTION
   This action arises out of the "Decision and Order on Changes to Rules 
of Operation 2, 9 through 14, and 17, and Rules 21 through 40" (the 
"Order") issued by the Commissioner of Insurance (the "Commissioner") on 
December 31, 2004, in the matter captioned "Revision of the Rules of 
Operation of the Commonwealth Automobile Reinsurers, Docket No. C2004-
02."(1)   Pursuant to this Order, the Commissioner has enacted a 
wholesale change in the Massachusetts involuntary automobile insurance 
market from a loss-sharing system to a risk-sharing system in violation 
of the enabling legislation, G.L. c. 175, Section 113H, as well as other 
sections of the General Laws.  The Order achieves this illegal change by 
creating an assigned risk plan called the Massachusetts Automobile 
Insurance Plan (the "MAIP") to replace the loss-pooling reinsurance 
entity called Commonwealth Automobile Reinsurers ("CAR").  The Order 
approved and adopted Rules of Operation for the MAIP, which implement 
the assigned risk plan, as well as proposed revisions to the existing 
Rules of Operation for CAR for the purpose of transitioning from CAR to 
the MAIP (collectively, the "New Rules").

   Plaintiff The Commerce Insurance Company ("Commerce") hereby appeals 
from the Commissioner's Order, pursuant to G.L. c. 175, Section 113H(E), 
on the grounds that the New Rules violate Massachusetts law.  Commerce 
also seeks a declaration, pursuant to G.L. c. 231A, Section 1, that the 
Commissioner's Order and the New Rules are invalid and requests 
injunctive relief prohibiting their enforcement.


  (1) In the Order, the Commissioner states that she regards her November 
23, 2004, order as "a final decision that has been subjected to some 
clarifications and minor revisions" and, therefore, the Order "should be 
read in conjunction with the November 23 Order."  (Order at 3.)  
Accordingly, for purposes of this Complaint, any reference to the defined 
term Order shall include not only the December 31, 2004, Order, but also the 
Commissioner's November 23, 2004, order.

PARTIES
   1.  Commerce is a Massachusetts corporation with a principal place of 
business at 211 Main Street, Webster, Massachusetts. Commerce is engaged 
in the business of writing motor vehicle insurance in the Commonwealth 
of Massachusetts.  Commerce is a member of CAR and is a Servicing 
Carrier pursuant to G.L. c. 175, Section 113H, and CAR's Plan of 
Operation and Rules of Operation.

  2.  The Commissioner is in charge of the Division of Insurance, a 
division of the Office of Consumer Affairs and Business Regulation.  The 
Commissioner is responsible for the administration and enforcement of 
the provisions of Chapter 175 of the General Laws of the Commonwealth of 
Massachusetts.  G.L. c. 175, Section 3A.

VENUE
   3.  Venue lies in Suffolk County pursuant to G.L. c. 175, Section 
113H(E).


BACKGROUND
  The Prior Residual Market Loss-Pooling Mechanism
  4.  G.L. c. 175, Section 113H, mandates that motor vehicle liability 
insurance be provided to applicants who are otherwise unable to obtain 
insurance-the "involuntary" or "residual" market-under a plan whereby 
the resulting "premiums, losses or expenses" of the involuntary market 
are apportioned among all licensed motor vehicle insurance companies.  
CAR is the entity responsible for operating this loss-sharing system.  
All motor vehicle insurers licensed to do business in Massachusetts are 
required to participate as members of CAR in a plan prepared by CAR's 
Governing Committee and approved, after public hearing, by the 
Commissioner.

   5.  CAR is administered by a Governing Committee composed of 
representatives of private insurance companies and associations of 
producers.  CAR is governed by a Plan of Operation ("CAR Plan") that 
serves as CAR's "charter and constitution" and sets forth "the framework 
in which CAR will conduct its affairs."  (Article X, CAR Plan.)  
Pursuant to the CAR Plan, CAR operates according to Rules of Operation 
and a Manual of Administrative Procedures.

   6.  Section 113H mandates that insurance carriers share the operating 
results-"premiums, losses, or expenses"-for policies in the involuntary 
market.  The Massachusetts involuntary market thus operates as a loss-
sharing reinsurance system.

   7.  The reinsurance system mandated by Section 113H creates a class 
of agents or brokers that may be appointed by CAR to an involuntary 
relationship with an insurance company.  G.L. c. 175, Section 113H(C).  
These agents or brokers are those that cannot obtain a voluntary 
relationship from an insurance carrier and are referred to as "Exclusive 
Representative Producers" or ERPs.  Once assigned, the agent becomes an 
ERP, and companies that are assigned these producers are called 
"Servicing Carriers."  The CAR Rules set forth a method for allocating 
ERPs among Servicing Carriers.

Page 5 of 9


   8.  Under Massachusetts law, a Servicing Carrier must accept all of 
the ERP's business; it must issue a policy to each applicant and remains 
responsible for servicing its policies.  With respect to the premiums, 
losses, and expenses associated with a particular policy or risk, a 
Servicing Carrier may choose to retain the risk itself or cede it to 
CAR, i.e., to the residual market loss-sharing pool.  Losses associated 
with ceded risks are shared by all companies even though the policy 
itself is written by the ERP's Servicing Carrier.

   The Commissioner's Directive for Movement from a Residual Market  
   Loss-Pooling Mechanism to an Assigned Risk Plan

   9.  By letter dated April 29, 2004, the Commissioner requested CAR to 
submit proposed changes to certain of the CAR Rules of Operation to 
ensure that the Rules operate in an efficient, fair, and equitable 
manner in distributing the financial burden associated with high-risk 
drivers and to implement appropriate claim handling processes.  The 
Commissioner stated that this goal could be accomplished only by 
switching from the then current loss-sharing system for distributing the 
financial burden of the involuntary market to a risk-sharing system 
known as an assigned risk plan ("ARP").

   10.  On June 29, 2004, the CAR Governing Committee held a special 
meeting to consider proposed transition amendments to the CAR Rules of 
Operation and proposed Rules of Operation for the MAIP (the "Proposal") 
in response to the Commissioner's April 29, 2004 request.  At that 
meeting, the CAR Governing Committee approved the Proposal, over 
Commerce's objection.  On June 30, 2004, CAR submitted the Proposal to 
the Commissioner.

   11.  The Division of Insurance held hearings to consider the 
Proposal, including revisions thereto, on July 22, 2004, October 29, 
2004, and December 17, 2004.  At each of these hearings, Commerce 
objected to the Proposal on various legal grounds.

   12.  On November 23, 2004, the Commissioner issued an order approving 
and adopting a revised version of the Proposal with certain of her own 
amendments.  In that order, the Commissioner stated that the enabling 
statute, G.L. c. 175, Section 113H, does not contain a "take-all-comers" 
mandate.  (November 23, 2004, order at 25.)  On December 31, 2004, the 
Commissioner issued the Order approving and adopting the Proposal as 
amended by the November 23, 2004, order with "some clarifications and 
minor revisions."  The Order creates and adopts the MAIP, Rules of 
Operation for the MAIP, and revisions to the CAR Rules of Operation to 
allow for a transition to the MAIP (collectively "the New Rules").

   The New Rules

   13.  The New Rules change the loss-sharing reinsurance system 
administered by CAR to an ARP administered by the MAIP.  Under the MAIP, 
a carrier is not required to accept all applicants, but rather may pick 
and choose the customers to whom it will issue policies.  Rejected 
applicants may be eligible for placement through the MAIP and 
involuntarily assigned to another carrier.  The carrier to whom the 
insured is assigned collects the premium and is itself responsible for 
the losses associated with that risk.  The ARP eliminates the prior 
reinsurance mechanism of pooling losses from ceded exposures.


Page 6 of 9 




   14.  The MAIP is to be preceded by a three-year transition phase.  
This transition began on January 1, 2005, with a number of changes to 
the residual market structure.

   15.  The MAIP is first introduced beginning on January 1, 2006, and 
the transition to the MAIP becomes final on January 1, 2008, after which 
any business not written on a voluntary basis is placed in the ARP.


COUNT I
(Appeal From the Commissioner's Order Pursuant to G.L. c. 175, 
Section 113H(E))

   16.  Commerce incorporates by reference the allegations contained in 
Paragraphs 1- 15 above as if fully restated herein.

   17.  G.L. c. 175, Section 113H(E), provides that "[a]ny ruling, order 
or decision of the commissioner under authority of this section shall be 
subject to review by appeal to the superior court department of the 
trial court of Suffolk county at the instance of any party in interest, 
which appeal shall be on the basis of the record of the proceeding 
before the commissioner.  Said court shall have jurisdiction to modify, 
amend, annul, review or affirm such action, order, finding or decision, 
shall review all questions of fact and of law involved therein, and may 
make any other appropriate order or decree.  Said court shall determine 
whether the filing of the appeal shall operate as a stay of any such 
order or decision of the commissioner."

   18.  The Order and the New Rules violate Massachusetts law, including 
the enabling statute, G.L. c. 175, Section 113H, because, among other 
things, they:

          a.  attempt to establish an ARP, notwithstanding that the  
              Legislature abolished such a plan as an option for the  
              involuntary market in the 1973 amendment to Section 113H;

          b.  allow Servicing Carriers to reject insurance applicants  
              in violation of the "Take-All-Comers" Law codified, in  
              regard to the involuntary market, in G.L. c. 175, Section 
              113H;

          c.  violate the twenty-carrier mandate of Section 113H;

          d.  violate the prohibition in Section 113H against informing  
              insureds of their placement in the involuntary market;

          e.  violate the credits mandate of Section 113H; and

          f.  eliminate the involuntary appointment of agents and 
              brokers who are unable to obtain a voluntary contract to  
              a servicing carrier in violation of Section 113H.

   19.  The Order and the New Rules violate the group marketing statute, 
G.L. c. 175, Section 193R, by making individuals who obtain insurance 
through a group marketing plan ineligible for the MAIP.

   20.  This Court should, therefore, annul the Order and the New Rules, 
pursuant to G.L. c. 175, Section 113H(E).

Page 7 of 9




COUNT II
(Declaratory Judgment Pursuant to G.L. c. 231A, Section 1)
   21.  Commerce incorporates by reference the allegations contained in 
Paragraphs 1-20 above as if fully restated herein.

   22.  An actual controversy exists between Commerce and the 
Commissioner concerning whether the Order and the New Rules are legal.

   23.  Such controversy has caused, and will continue to cause, harm to 
Commerce, including actual and threatened monetary loss, difficulty in 
making business decisions, and other hardships that justify the 
declaratory and other relief sought herein.

   24.  Accordingly, Commerce is entitled to declaratory relief, 
declaring that the Order and the New Rules violate Massachusetts law, 
including the enabling statute, G.L. c. 175, Section 113H, because, 
among other things, they:

           a.  attempt to establish an ARP, notwithstanding that the  
               Legislature abolished such a plan as an option for the  
               involuntary market in the 1973 amendment to Section 113H;

           b.  allow Servicing Carriers to reject insurance applicants  
               in violation of the "Take-All-Comers" Law codified, in  
               regard to the involuntary market, in G.L. c. 175, Section 
               113H;

           c.  violate the twenty-carrier mandate of Section 113H;

           d.  violate the prohibition in Section 113H against informing 
               insureds of their placement in the involuntary market;

           e.  violate the credits mandate of Section 113H; and

           f.  eliminate the involuntary appointment of agents and  
               brokers who are unable to obtain a voluntary contract to  
               a servicing carrier in violation of Section 113H.

   25.  In addition, Commerce is entitled to declaratory relief, 
declaring that the Order and the New Rules violate the group marketing 
statute, G.L. c. 175, Section 193R, by making individuals who obtain 
insurance through a group marketing plan ineligible for the MAIP.

   26.  In connection with the requested declaratory relief, Commerce 
seeks an injunction, pursuant to G.L. c. 231A, Section 2, enjoining the 
Commissioner from implementing and enforcing the Order and the New 
Rules.










Page 8 of 9





   WHEREFORE, Commerce respectfully requests that this Court:

   1.  after a decision on the merits, enter a declaratory judgment 
declaring that the Order and the New Rules are invalid because they 
violate Massachusetts law;

   2.  after a decision on the merits, enter a declaratory judgment that 
a "take-all-comers" mandate is contained in G.L. c. 175, Section 113H, 
contrary to the Commissioner's pronouncement in her November 23, 2004, 
order;

   3.  after a decision on the merits, enter an order annulling the 
Order; 

   4.  after a decision on the merits, permanently enjoin enforcement 
and/or implementation of the Order and the New Rules; and 

   5.  grant such other and further relief as is just and proper, as 
well as the costs of this action.
